We are ALWAYS happy to combine your purchases to save on shipping charges! ECrater does not automatically adjust your invoice for multiple items when you're done shopping, so if you send payment thru Paypal to avoid the item being sold in the interum, we can refund the overpayment, or, you can say you'll be paying by money order and wait for an adjusted Paypal bill! Thank you for "shopping buy", or rather, stopping by!
